How much does fiber distribution box welding cost per core

For most commercial projects, expect to pay $50–$150 per fusion splice point - but that number can swing in either direction based on the factors below. This refers to the cost of electrical power used for welding. Direct labor cost of welding usually covers the wages of the welder and the helper who helps. I usually bill T&M, but it works out to about $175-250 for setup/teardown per site and $4-7 per fiber for prep in a new tray in an existing case and splicing depending on if it's flooded or dry cable. Add another $50-75 to prep a new case endspan or $100-150 for a new case midspan with overcut on. Fiber optic splicing costs vary widely depending on project size, location, fiber type, and site conditions. The "per splice" rate is the most.
